What is the purpose of a busbar in a solar inverter?

The purpose of the busbar is simple yet crucial as it separates the cells to conduct direct current from the photons and transfer it to the solar inverter to convert the current into alternating current.

What is multi busbar technology?

Super Multi BusBar (SMBB) solar cell technology is an advanced photovoltaic (PV) technology that involves using multiple thin copper or silver strips, known as “bus bars,” to connect the solar cells in a solar module.

Why is multi-busbar technology important for photovoltaic cells & modules?

With the multi-busbar design, module performance can be increased because of the reduction in the total series resistance of the interconnected cell strings and also because of improved light utilization owing to the round wires. There are four key advantages to using MBB technology for photovoltaic cells and modules:

Who presents multi busbar connector prototype at PVSEC?

SCHMID Group 2012, “SCHMID presents multi busbar connector prototype at PVSEC”, Press Release, September 18th. Schindler, S. et al. 2013, “Soldering process and material characterization of miniaturized contact structures of a newly developed multi busbar cell metallization concept”, Proc. 28th EU PVSEC, Paris, France.

What are busbars made of?

The busbars are generally made of copper plated with silver (Ag) paste to enhance the current conductivity in the front side and to minimize the oxidation at the backside. Similarly, multiple busbars are used to wire solar cells together to generate high voltage electricity.

What is busbarless cell interconnection?

The company has deployed a notable innovation – busbarless cell interconnection, which it calls Hyper-Link. The approach replaces traditional busbars with a wire mesh that bonds and forms an electrical contact with the cell without the use of conventional high-temperature soldering.
